CAR-COUPLING.

SPECIFICATION forming part 01' Letters Patent No. 654,941, dated July 31, 1900. Application filed March 8, 1900- $eria1 No. 7,854. I (No model.)

To all whom it, may conceive: v

Be it known that I, MARK A. BROWN, a citizen of the United States, and a resident of Georgia, have invented certain newan'd useful Improvements in Oar-Oouplin gs, of which the following is a full, clear, and exact description.

My invention relates to car-couplings in which a hook on one car is adapted to interlock with a retaining device on the other car.

The object of my invention is to provide a simple car-coupling of the above-indicated class in which the hook may be readily reversed and detached and in which a yielding latgral motion of the hook is allowed at each en The invention consists in the particular construction and arrangement of parts here inafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of two coupling-heads constructed according to my in vention in a slightly separated position. Fig. 2 is a sectional plan of the coupling with the parts connected, and Fig. 3 is a sectional elevation on line 3 3 of Fig. 2 with the coup ling-hook omitted.

In carrying out my invention I employ a hollow draw-head or coupling-head A, pro vided with a shank A, which is connected with the car in any approved manner. At the outer end of the head A is an opening or throat A which communicates with a chamber A Within said chamber are located springs B, secured at their rear ends by bolts 0 and having at their front ends curvedportions B, forming seats for pins D, mounted to slide vertically in transverse slots A in the head A and also capable of moving laterally in said slots. The springs engage the outer surfaces of the pins and have a tendency to force them inward against central projections A A of the head A. The pins D have heads D, connected by links 'E with crank members F upon a shaft G, extending ings H. This shaft may be turned by means of handles G. Douglas, in the county of Oolfee and State of In connection with the parts so far described I employ a coupling-hook I, having anarrow-shaped head I and the shank 1 which immediately adjacent to the head I is of aboutv the same width as the projections A A of thedraw-head A. At its other end the hook has two perforations or through-apertures at about the same distance apart as the inner ends of the transverse slots A. These two perforations are located laterally. of the longitudinal axis of thehook. In order to enable the hook to be used in connection with ordinary car-couplings, I may provide'it with'another through-aperture 1 located in the median longitudinal plane of the hook, as shown in Fig.

The operation of my improved car-coupling is as follows: The pins D of one draw-head A are passed through the slots A and through the two adjacent perforations of the hook I, so that said hook is connected with the drawhead, as shown in Fig. 2, and projects there: The cars being' from, as shown in Fig. 1. then moved together, the arrow-head Ipasses between the pins D of the next car and forces them apart against the tension of the springs B, the pins finally catching behind the arrowhead, as shown in Fig. 2. The cars arethen securely connected and cannot become uncoupled'accidentally. Uncoupling is generally eifected by detaching the arrow-head of the hook from the car with. which it is engaged. To this end the shaft G of said car is turned by means of the handle G, and this will cause the crank-arms F and pins D to be raised suffi ciently to release the head of the hook. It is just as easy, however, by a corresponding manipulation to uncouple cars by detaching the shank of the hook from the car with which it is connected, (thus leaving the hook on the car which-receives the arrow'-head,) and this manner of uncoupling may be used under special circumstances, although, of course, it is preferable to leave the hook on the car which receives its shank, so that the hook will remain in readiness for coupling.

B B enable the pins D to yield laterally, not

. havinga headadapted to force the pins apart pressing said pins together, a coupling-hook having a head adapted to force thepins apart in coupling, and a shank having perforations adapted to receive the pins of another car, to

It will be'lseen that the draw-heads or coupling-heads A are constructed exactly alike, so that either the shank or the arrow-head of the hook I may be connected with the drawhead and a hook may be readily reversed or transferred from one car to another. A By providing the aperture 1 I enable the hook to be used in connection-with the well-known form of car-couplings in which a pin is passed through the end of the hook.

3. A car-coupling comprising a hollow head having transverse slots, pins alining transversely and movable in said slots vertically and transversely, a coupling-hook connected with a car at one end and having at its other end a head adapted to be locked by the said pins, and means, for operating the pins to release the hook.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
